bile juice

Answer 2

Bile is continuously secreted in small amounts by liver cells, stored in gall bladder, and released into duodenum on cholecystokinin $(CCK)$ stimulation. It is a yellowish green or greenish blue alkaline $(pH \,7.7)$ fluid. The bile pigments are bilirubin and biliverdin. The bile pigments result from the breakdown of haemoglobin in RBCs, giving the bile its colouration, which in turn affects the colour of the faeces nodes etc.
